Description
Technical Field
The utility model relates to the field of automobile parts, in particular to a hub bearing unit with a universal sealing ring.
Background
The hub bearing is a part applied to an axle of an automobile and used for bearing and providing accurate guide for rotation of a hub, and is an important component for loading and rotation of the automobile. Most of the magnetic encoders of the traditional automobile hub bearing units are of external structures, tiny particles in air are easy to adsorb to form thick mud dirt, and the magnetic encoders are easy to damage due to the impact of splashed small stones, so that the magnetic encoders are low in service life.
As shown in fig. 3, in general, a second-generation hub unit with a sealing assembly is designed, in order to achieve perfect sealing performance, two sealing rings are often designed to be respectively matched with a magnetic ring and a dust cover, so that there is a problem that the sealing lips of the two sealing rings are different in length (the part where the magnetic ring is installed needs a longer sealing lip), and cannot be used uniformly, and the production cost is increased.
Disclosure of Invention
In order to overcome the defects of the background technology, the utility model provides a hub bearing unit with a universal sealing ring, which mainly solves the problem that the sealing ring of the existing hub bearing unit is low in universality.
The technical scheme adopted by the utility model is as follows:
the hub bearing unit with the universal sealing ring comprises an outer ring and an inner ring, a retainer is arranged between the outer ring and the inner ring, a rolling element is arranged on the retainer, a first sealing ring and a first sealing cover are arranged on one side of the rolling element, the sealing ring is provided with a plurality of first sealing lips matched with the first sealing cover, and a magnetic ring is arranged on the outer side of the first sealing cover; the rolling piece is provided with a first sealing ring and a first sealing cover at the other side, the first sealing cover comprises an outer plate, a groove extending towards the first sealing ring is arranged on the outer plate, the first sealing ring comprises a first sealing lip, and the first sealing lip is in sealing fit with the inner wall of the part of the outer plate provided with the groove; the first sealing ring and the second sealing ring have the same structure.
The rolling element is a rolling ball.
The side wall at one end of the groove is perpendicular to the end face of the bottom of the groove, and an included angle a formed by the side wall at the other end of the groove and the end face of the bottom of the groove is an obtuse angle.
The included angle a is 110-130 degrees.
The included angle a is 120 °.
The groove is an annular groove.
The rolling ball is made of stainless steel.
The beneficial effects of the utility model are as follows: the utility model provides a hub bearing unit with a universal sealing ring, wherein the sealing ring can be matched with two ends, and the universality is strong.
Drawings
FIG. 1 is a schematic cross-sectional view of one embodiment of the present utility model.
FIG. 2 is a partial schematic view of an embodiment of the present utility model.
Fig. 3 is a schematic diagram of the prior art.
Detailed Description
The utility model is further described below with reference to the accompanying drawings: as shown in the figure, a hub bearing unit with a universal sealing ring comprises an outer ring 1 and an inner ring 2, a retainer 3 is arranged between the outer ring and the inner ring, a rolling element 31 is arranged on the retainer, a first sealing ring 41 and a first sealing cover 42 are arranged on one side of the rolling element, the sealing ring is provided with a plurality of first sealing lips 411 matched with the first sealing cover, and a magnetic ring 412 is arranged on the outer side of the first sealing cover; the other side of the rolling element is provided with a second sealing ring 51 and a second sealing cover 52, the second sealing cover comprises an outer plate 6, a groove 61 extending towards the direction of the second sealing ring is arranged on the outer plate, the second sealing ring comprises a second sealing lip 511, and the second sealing lip is in sealing fit with the inner wall of the part of the outer plate provided with the groove; the first sealing ring and the second sealing ring have the same structure. The second sealing cover is applicable to a first sealing ring and a second sealing ring which are common in use, the first sealing cover is of the same size, and the length of the first sealing lip is also shorter because the first sealing cover with the magnetic ring is shorter, and the second sealing ring with the same structure as the first sealing ring can be also used in an adapting way after the second sealing cover with the groove is adopted. The depth of the grooves can be set according to the thickness of the magnetic ring.
In this embodiment, the rolling elements are balls as shown.
In this embodiment, as shown in the figure, one end side wall of the groove is perpendicular to the bottom end face of the groove, and an included angle a formed by the other end side wall of the groove and the bottom end face of the groove is an obtuse angle. The front of the inlet of the sealing structure is effectively reduced from being flushed, and when the hub unit rotates at a high speed, the muddy water can be thrown out under the action of centrifugal force.
In this embodiment, as shown in the figure, the included angle a is 110 ° to 130 °. Is in a size-changing range and has better use effect.
In this embodiment, the included angle a is 120 ° as shown.
In this embodiment, as shown, the groove is an annular groove.
In this embodiment, as shown, the rolling balls are made of stainless steel. The service life is longer.
